Hi thanks for contacting health care magic. Apart from chest pain you have mentioned not any other symptoms .... You have chronic chest pain.... Its better you consult pulmonologist for your auscultation and respi examination. Spirometry that is pulmonary function test done to diagnose whether any restrictive or obstructive pulmonary disease if present.... Chest x ray also useful.... Second if you have history of trauma then muscular tear can lead muscular chest pain. If your ribs tender to touch then costochondritis can be there. For that brufen given.... If your pain severe and constricting type then ECHO done for rule out ischemic problem. Take care. With proper examination and above investigation your diagnosis will be revealed. Consult pulmonologist for that. Take care
